how electric charges can be used to create a magnetic field
(how I know, just took it, the test I mean)
And I gather that instead of trying it on your own, you want me to do it for you.
The force of gravity between two objects always involves the product of
both of their masses.
"Weight" is the force of gravity between a planet and an object on its surface,
so it depends on both masses.
When a rock, a space probe, or an astronaut goes to a different planet, its/his
mass doesn't change, but the mass of the body they're standing on is different.
So the weight of the rock or the astronaut is different from what it is on Earth.
